(chat, BBS, e-Mail, … ) qustion to nemoton@computer.org

Just now in Akihabara where hobby overflows Here is OTAKU Culture in the real space. Otaku every where in Akihabara … qustion to nemoton@computer.org

Just now in Akihabara mixed culture qustion to nemoton@computer.org

What is Akihabara ? I think that Akihabara is a city that grows up by the hobby and the demand. I recommend you walk around Akihabara. You can see a lot of things. qustion to nemoton@computer.org

2-channel qustion to nemoton@computer.org

What is 2-channel? BBS? There are only character/ ASCI I code. You can see many pictures drew by character/ ASCI I code. qustion to nemoton@computer.org

happiness What ’ s mean? For example ♪ ♪ ｖ ( ⌒ ｏ ⌒ ) ｖ ♪ ♪ v(= ∩ _ ∩ = ) o(^ -^ )o ( σ ^ ▽ ^ ) σ qustion to nemoton@computer.org

sadness What ’ s mean? For Example (T_T) ヽ ( ≧ Д ≦ ) ノｳ ﾜ ｧ ｧ ﾝ !! ( ´∩ ｀ 。 ) qustion to nemoton@computer.org

What ’ s mean? surprise For example ( ； ‾Д ‾） なんですと ？ ∑ q| ﾟ Д ﾟ |p ﾜ ｵ ｫ (* ﾟ 0 ﾟ ) ﾊ ｯ (((((( ; ﾟ Д ﾟ ))))) ｶ ﾞ ｸ ｶ ﾞ ｸ ﾌ ﾞ ﾙ ﾌ ﾞ ﾙ qustion to nemoton@computer.org

What ’ s mean? anger For example こ ら ( ` Д ´ )y-* ) ゜ Д ゜ )y _~ ~ ~ ムカ ッ ( ‾∩ ‾ # ( ▼ 皿▼ ;) ｳ ｷ ｰ ｯ (" ‾д ‾ ) けっ ! qustion to nemoton@computer.org

New Language? New culture? A new language was born on BBS. I think that the Japanese tends not to put out feelings to the table so much. On BBS, there is no face to face communication. But they want to convey their emotions to the other people on BBS in their home. It was led by the spread of the personal computer and the Internet. So, they can communicate without face to face communications using speech, facial expression and gesture. qustion to nemoton@computer.org

Image analysis using YIQ systems (1) original (2) I(YIQ) (3) extract only face (5) Y(YIQ) (6) = (5)-(4) (4) Face mask The YIQ system is the color primary system adopted by National Television System Committee (NTSC) for color TV broadcasting. The YIQ color solid is made by a linear transformation of the RGB cube. Its purpose is to exploit certain characteristics of the human eye to maximize the utilization of a fixed bandwidth. The human visual system is more sensitive to changes in luminance than to changes in hue or saturation, and thus a wider bandwidth should be dedicated to luminance than to color information. Y is similar to perceived luminance, I and Q carry color information and some luminance information. The Y signal usually has 4.2 MHz bandwidth in a 525 line system. Originally, the I and Q had different bandwidths (1.5 and 0.6 MHz), but now they commonly have qustion to the same bandwidth of 1 MHz. nemoton@computer.org
